Therefore God exalted him to the highest place
and gave him the name that is above every name,
that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father.
Philippians 2:9-11
Observation: Paul discusses the good work and good practices of the church in Philippi. He hopes to someday leave prison and come see them, but if he cannot he wants to encourage their faithfulness. In this, he discusses the nature of Jesus, and that he is exalted as the Messiah, and that one day everyone will acknowledge Jesus as Lord, giving glory to Yahweh.
And who is 'everyone'? Paul says it will be everyone in heaven, on earth, and under the earth. However, "under the earth" isn't a clear description of a location.
-- In heaven = Those dead who have received eternal blessing in Yahweh ... or those never born
-- On earth = All the living
-- Under the earth = Those dead who have received damnation in hell ... or just those dead
The common interpretation is that this was all just Paul's way of saying "everyone". Every person past, present, and future will bow and worship Jesus as Messiah, even if they never before believed that. At some point, there will be a great revelation, and even the most evil person who rejected Jesus will come to the realization that the Lord is real, Jesus is the savior of the world, and their most proper act is to bow and worship him.
Application: I started with questions about this interpretation of this passage ... a common reading of these words could lead to an understanding we're talking about the future worshippers being the angels in heaven, and the believers on earth both alive and dead. However, as I think on this and pray on this, I am more inclined to accept the common theology. There will be a day when all these people I see every day who actively reject everything about the Lord, about Jesus, and about faith, will bow on their knees and declare with all their heart that Jesus Christ is Lord.
I wonder, will that be enough to save them? Will bowing to worship in the face of some event that removes any and all ability to even fathom any other truth about the entire universe, be acceptable as 'faith'?
Here is the answer to this question I receive: That is not my concern to know and understand. My job is just to rejoice in knowing that some day everything about Jesus will be proven to such a degree that no one who has ever opposed it will be able to stand. They will all surrender, realizing their errors. I can celebrate that now, during every hard and frustrating and sad day, knowing that this 'someday' is a forgone conclusion. How that affects the salvation of those individuals is not mine to figure out or even think upon.
Prayer: Lord, I do thank you for the joy in knowing that one day everyone will just know the truth. I celebrate that future day in my heart today. May I know you better today. Please keep me strong in my faith, in my love for others, and in my obedience today. Amen.
